Commands and Responses for Controller Link Units
Section 6-5
Status 2 (response):
For C200HX/HG/HE, CVM1, and CV-series Controller
Link Units, always set to 00 (Hex). For CS/CJ-series and CQM1H-series
PLCs, the Unit’s setting status is returning in the following configuration.
Status 3 (response):
Error information. The configuration is as follows:
Note
With CS/CJ-series Optical Controller Link Units, this bit will be 1, even if the
Unit is mistakenly connected to an Optical SYSMAC LINK Network.
Status 5 (response):
Error information related to the Unit and the PLC. The
configuration is as follows:
A network parameter error, data link table error, or routing table error occurs if
an error is discovered when the parameters and tables are checked at power
up.
A PLC system setting errors occurs if the Controller Link Unit is not properly
recognized by a CS/CJ-series, CVM1, or CV-series PLC.
A PLC model error occurs if a C200HX/HG/HE Controller Link Unit is
mounted to another type of PLC.
Count 1 to Count 8 (response):
The total number of times for each of the
items listed below is returned as 1 byte of hexadecimal data.
Count 1: Number of CRC errors
Count 2: Number of token re-sends
Count 3: Number of token returns
Count 4: Number of token timeouts
Count 5: Number of polling timeouts
Count 6: Number of controller changes
Count 7: Number of active node changes
Count 8: Reserved for system use.
For the C200HW-CLK21 and CVM1-CLK21,
Count 7: Number of active node
changes
is disabled.
For the CS1W-CLK23 and CJ1W-CLK23,
Count 5: Number of polling timeouts
is disabled.
